When the US Supreme Court announced its landmark 6-3 decision to take race out of the equation for college and university admissions, it did more than just bring Affirmative Action in higher education to a screeching halt. It also fired a warning shot across the bow of businesses and governmental agencies across America: the days for workplace diversity, equity, and inclusion (DEI) programs that violate the Equal Protection Clause of the 14th Amendment have an expiration date. In The Adversity of Diversity, award-winning political scientist Carol M. Swain and collaborator Mike Towle offer an insightful look at DEI’s inception and evolution into a billion-dollar industry. Swain and Towle explain why DEI’s days are numbered, and how we as a people can move beyond divisiveness toward the unity promised by our nation’s motto, e Pluribus unum, “out of many, one.”
